Since you are not using an Apple wifi card, take the machine somewhere like a wifi hotspot to see if it's the machine or the router.
"same MAC filtering"
Sorry but if you look at our forum sticky we don't suggest that feature. It and SSID no broadcast does not add to security and can cause failures.
OK, I had previously had a wireless network set up with my DSL line. (Zyxel router hooked up to my Mac and Zyxel wireless card for my ancient Sony VAIO). When I moved I switched to cable modem. I've figured out how to clone the MAC addy on my router to make it match my Mac, and plugged the cable modem into the router. I now have Internet access on the Mac via the router, yay.
Here is the problem - although my router is setup as a wireless access point (using DHCP, broadcasting its SSID), I cannot see the router in the list of wireless servers from the Vaio. Nothing has been changed in the router settings in regards to the Wireless Access Point. Same encryption, same password, same MAC filtering as before - and the MAC addy on the Vaio has not been changed. (I figured I wouldn't need to, because the only thing that cares about the MAC addy is the cable modem, and it's being fooled by the router. Anyway even if I did need to do that, I would expect to be able to see the SSID of the router in the list of wireless servers, even if I couldn't connect to it.)
What am I missing? Should I change the MAC addy on the Vaio as well? Should I check for updated firmware for the router? Any ideas greatly appreciated.
